Replaces the doser contraption on a factory Mazzer Super Jolly SJ grinder. Convert your Mazzer SJ to a single-dose grinder!

For now black is the only color but feel free to contact me for custom colors.

Our design comes with a 304 stainless steel tube which is hand polished to provide a reflective surface and smooth edge. There is a hole near the chute so you may insert your bellows and blow out the retention.
